Lithium hexamethyldisilazane
Lithium bis(trimethylsilyl)amide is a lithiated organosilicon compound with the formula LiN(Si(CH3)3)2. It is commonly abbreviated as LiHMDS or Li(HMDS) (lithium hexamethyldisilazide - a reference to its conjugate acid HMDS) and is primarily used as a strong non-nucleophilic base and as a ligand. Like … Meer weergeven LiHMDS is commercially available, but it can also be prepared by the deprotonation of bis(trimethylsilyl)amine with n-butyllithium. This reaction can be performed in situ. HN(Si(CH3)3)2 + C4H9Li → LiN(Si(CH3)3)2 … Meer weergeven Like many organolithium reagents, lithium bis(trimethylsilyl)amide can form aggregates in solution. The extent of aggregation depends on the solvent. In coordinating … Meer weergeven As a base LiHMDS is often used in organic chemistry as a strong non-nucleophilic base.
